Allocation of memory

[Yair Goldel]

Hi All
I have simple program that make allocation of memory .
With one user she allocate 1010M and with user root she allocate 1900M
I can see with "ulimit -a" that for user root data is unlimited and with my user its limit to 1G
What i need to change to allow my user to alloc more then 1G

You need to change the kernel parameter values of maxdsiz and maxssiz to higher values.

Best regards,

Have you tried "ulimit unlimited" for that user?

my maxdsize is 3.2GB maxssize is 209M

i've compiled the application using MAGIC attributes - in some machines i get 1010M others i get 1900M.

ulimit works on some - at others i still get 1010MB

[Yair Goldel]

i've worked according to the attached document

[Yair Goldel]

ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 1048576
stack(kbytes) 8192
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 2048

how do i change the data(kbytes)????

The maximum data segment size for a process is specified via the 'maxdsiz'
kernel parameter. For the value of maxdsiz, use integer that are multiple
of 4096 bytes, the system pagesize.

i currently have 3221225472
but still have on more than 1010MB

Are you running 64 bit application? What is your maxdsiz_64?
